Recorder Program Identifying Information Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional timer-recording methods for TV programs are inaccurate due to reliance on set times, which can differ from actual broadcast times, especially in live events where broadcast durations are extended, leading to incomplete recordings.
Innovation Solution
A recorder equipped with a program identifying information detector and recording operation controller that detects program start, duration, and end times, and controls recording operations based on this information, allowing for accurate and flexible recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If timer-recording is set based on built-in timer set time, then the recording operation can be automated, but the recording start time becomes inaccurate when broadcast time differs from set time
Solution Approach 1:
The system continuously monitors actual broadcast time through the program identifying information detector and compares it with the scheduled broadcast time. When a time difference is detected, the recording operation controller automatically adjusts the recording start time accordingly, ensuring accurate recording despite changes in broadcast schedule
Solution Approach 2:
The recorder automatically detects program identifying information and adjusts recording operations without requiring user intervention. The system self-corrects timing discrepancies by monitoring actual broadcast duration and automatically modifying recording parameters, eliminating the need for manual time adjustment by the user
2Ease of operation
If recording is set based on fixed time schedule, then the recording operation is simple to control, but the recording becomes incomplete when preceding program is extended
Solution Approach 1:
The recording operation controller dynamically adjusts recording parameters based on actual broadcast duration. Instead of using fixed time schedules, the system continuously monitors program identifying information and adapts recording start and end times according to actual broadcast conditions, ensuring complete recording while maintaining ease of operation
Solution Approach 2:
The system uses feedback from the program identifying information detector to continuously monitor actual broadcast time and adjust recording operations accordingly. This feedback mechanism ensures that recording remains complete even when program duration changes, while the user simply needs to set the initial recording parameters without managing timing adjustments

AI summary
In order to record a program provided by a program broadcasting device, a recorder (5) that receives program identifying information provided by a program information providing device to record the program includes: a program identifying information detector (10) for detecting the program identifying information at least at one timing of start, duration, and end of the broadcasted program; and a recording operation controller (20) for controlling recording operation based on a detection result of the program identifying information detector (10). The recording operation controller (20) includes: a recording start/end determining section (21) for staring and/or ending the recording operation based on the detected program identifying information; and a recorded program determining section (22) for determining the program being recorded based on the program identifying information detected while the program is recorded.
